Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed June 13, 1911. Serial No. 632,903.

To all whom it may concern:

Be it known that 1, WILLIAM S. Sonncitizen of the United States, res1d-BURY, a 0 ing at Sedro Woolley, 1n the county of Skagit, State ofWashington, have lnvented certain new and useful Improvements inRoller-Bearing Sash-Holders; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to window sashes, and particularly one soconstructed that the use of pulleys and sash balances are eliminated,but at the same time the sashes may be raised and lowered in an easymanner and held in their adjusted open position.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimhereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :-Figure 1 is a front elevation of a sash and frame, theside sec tions being partly broken away. Fig. 2 is an end view of thesashes, one side of the same being presented. Fig. 3 is a sectional viewon line 3-3 of Fig. 1, when the lower sash is in its raised position.

Referring to the drawing, the numeral 1 designates a window frame havingguide ways 2 provided, and in which the upper and lower sashes 3 and 4,respectively, are slidably mounted.

The lower sash i has its side rails provided in their outer faces withchannels 5, the channel in the left rail being slightly deeper at itsupper end than at its lower end and is narrowed slightly at its lowerend. The channel formed in the right rail of the lower sash is formed ina manner reversely to that in the left rail, the object of thisformation will be hereinafter described.

Formed in the side rails of the upper sash are channels 6, the channelin the left rail being wider and deeper at its lower end than at itsupper end. The channel formed in the right rail is deeper and wider atits upper end than at its lower end.

7 hen the sash and frame are in their assembled position rubber balls 7are placed in the channels formed in the upper and lower sashes so thatthey will be in yielding contact with the face of the guide ways 2. Fromthis construction it will be seen that when it is desired to raise thelower sash, the balls 7 having been previously placed within the upperends of the channels 5, the upward movement of the sash will cause theballs to travel in a downward direction, the ball in the channel of theleft rail traveling downwardly and into the narrowed lower portion ofthe channel, which travel causes the ball therein to be compressed andprojected outwardly to frictionally hold the sash in its raisedposition. The ball in the channel in the right rail travels downwardlyfrom the shallow and narrowed portion of the channel to the widened anddeeper lowered portion, so that the sash will be held from one side orthe other when in its different raised positions.

The operation of the balls in the channels of the upper sash is the sameas that of the lower sash, with the exception that the balls are placed,when assembling the frame and sash, in the lower ends of the channels 6formed in the side rails of the sash.

it should be noted that the balls 7 are constructed preferably fromrubber or other resilient material, and upon the operation of the windowsash they will be compressed and forced to the smaller ends of thechannels in which they are located, and owing to their resilient naturewill frictionally engage the window frame permitting the sashes to beraised and lowered by force, and holding the same in their variousadjusted positions by their resiliency which counteracts the weight ofthe sashes and prevents any undesired movement when the same has beenadjusted.

It will be seen that owing to the tapered arrangement of the channels 5and 6, one side of the window frame will at all times be frictionallyengaged by the balls.

What is claimed, is v In a Window construction, the

tion with a frame; of a sliding sash therein having longitudinalchannels in the outer 5 faces of the stiles thereof, said channels beingWider and deeper at one end other the Wider and deeper ends of saidchannels being disposed at opposit the latter, and

whereof, I afix my signae of tWo Witnesses.
